PDF: 30 MB/file, 80 MB total, 120 pages. Images: 20 MB/file, 24 MP, 20 files.

Automatic processing · light on device, heavy on server

PDF outputs keep visible pages and text. Links, interactive forms, annotations and digital signatures are not preserved.

When should you use this tool?

Combine a CV and attachments, invoices or course chapters into one PDF. A single document is easier to send and read than a collection of separate files. Choose the order yourself and get the result without creating an account.

How to get your result

Select at least two PDFs and use the move controls to arrange the documents. Check the previews before creating your file. To include a photo, first convert it with Images to PDF, then add that PDF to your merge. Keep the original files for later changes.

A question?

Can I merge PDFs and photos together?

The merger accepts PDFs. Convert JPG, PNG, WebP or HEIC photos with Images to PDF first, then merge the resulting PDF with your documents.

Are my files uploaded?

Light tasks stay in your browser. Heavy tasks, or local processing lasting over eight seconds, automatically use the server when available. Temporary files are deleted after processing or failure. No account needed.
